本研究利用酿酒酵母作为生物吸附剂吸附重金属Cu2+,探讨了酿酒酵母在不同条件下对重金属铜离子的吸附能力。研究结果表明:当Cu2+ 的初始浓度为1 g/L,酵母投加量为5 g/L,吸附时间30 min 时,Cu2+ 的吸附率达到最高,为92.80%;当Cu2+ 的初始浓度为1 g/L,酵母投加量为5 g/L,吸附时间为45 min 时,Cu2+ 的吸附率最高,达到92.30%;当转速在100 r/min 时,Cu2+ 的吸附率最高,为94.33%;当pH 为7 时Cu2+ 的吸附率最高,为95.48%;当温度为30 ℃时,Cu2+ 的吸附率最高,为94.19%。最佳的吸附条件为:吸附时间45 min,转速100 r/min,pH 为7,温度30 ℃。
- Abstract:
-
Saccharomyces cerevisiae was used as a biosorbent to adsorb heavy metal Cu2+, and the adsorption capacity of saccharomyces cerevisiaee on heavy metal copper ions under different conditions was discussed.The results showed that: when the initial concentration of Cu2+ was 1 g/L, yeast dosage was 5 g/L and adsorption time was 30 minutes, the adsorption rate of Cu2+ reached a maximum of 92.80%; when the speed at 100 r/min, the adsorption rate of Cu2+ reached a maximum of 94.33%; when the pH was 7, the adsorption rate of Cu2+ reached a maximum of 95.48%; when the temperature was 30℃ , the adsorption of Cu2+ reached a maximum of 94.19%. Therefore, the best adsorption condition was when the adsorption time was 45 min, the speed was 100 r/min, the pH was 7, and the temperature was 30℃.
